Abstract: An operating system kernel includes an attach mechanism and a detach mechanism. In addition, processes are tagged with an access attribute identifying the process as either a client process or a server process. Based on the access attribute, the operating system kernel lays out the process local address space differently depending on whether the process is a client process or a server process. A server process can “attach” to a client process and reference all of the client process' local storage as though it were its own. The server process continues to reference its own process local storage, but in addition, it can reference the other storage, using the client process' local addresses. When access to the other storage is no longer needed, the server process can “detach” from the client process. Once detached, the other storage can no longer be referenced.

Abstract: In one aspect of the invention, a method provides a calibrated critical-failure model for a printing process of a critical feature by virtue of a classification of an optical parameter space according to at least two print-criticality levels. Print failure of a respective critical feature is judged on the basis of a print-failure criterion for the critical feature. The respective print-criticality level is ascertained from test-print-simulation data at a sampling point of a process window for a given point in an optical-parameter space, and from a failure rule. An advantage achieved with the method is that it comprises ascertaining the predefined optical-parameter set from the test-print-simulation data at only one sampling point of the process window, which sampling point is identical for all test patterns. This saves processing time and processing complexity by reducing the number of ascertained optical-parameter sets and their processing in the subsequent scanning and classifying steps.

A timeout duration can be specified, and may be set by the notification, so that the diagnostics will be performed within the timeout period even if a time of low activity has not occurred by the expiration of the timeout.
